INFORMATIVNE KARAKTERISTIKE POTROŠNJE VODE U HOTELIMA NA PODRUČJU RIJEKE

This paper analyses the quality of municipal water in the hotels in the area of Rijeka as well as the amount of its consumption. This paper also discusses the probability of contamination and consequences that tourists and citizens who use such water could suffer. The area of this water system belongs to the karst relief marked by a significant underground circulation and high sensitivity to external influences which leads to contamination. Considering the peculiarity of karst aquifers, during heavy rainfalls after long dry periods there is a possibility of turbidity and microbiological water contamination which usually are not long lasting. Despite occasional hydro geological problems, the public utility company has organised a system for monitoring water quality in water supply system and sanitary correct drinking water is discharged into the system. Besides being drinking water, that water is clean and has good quality of mineral composition. Although Rijeka’s water supply system is leading in Croatia according to security of water supply and drinking water, consumption in hotels is mainly related to sanitary water, because tourists do not have the habit of drinking tap water or they are not enough informed about such possibilities.U radu su analizirani kvaliteta komunalne vode u hotelskim objektima na prostoru Rijeke kao i količina potrošene vode. Razmatrane su i vjerojatnosti onečišćenja te posljedice koje onečišćenje može stvoriti turistima i stanovništvu koje bi koristilo takvu vodu. Područje ovog vodoopskrbnog sustava pripada kršu za koji je značajna podzemna cirkulacija vode, te velika osjetljivost na vanjske utjecaje, odnosno na moguća onečišćenja. Obzirom na specifičnost krških vodonosnika, za vrijeme jakih kiša, nakon dužih sušnih perioda, moguća su zamućenja i mikrobiološka onečišćenja vode koja obično nisu dugotrajna. Unatoč povremenim hidrogeološkim poteškoćama, Komunalno društvo ima organiziran sustav praćenja kvalitete vode u vodovodu te se u sustav ispušta zdravstveno ispravna pitka voda. Osim što je pitka, ta je voda čista i kvalitetnog je mineralnog sastava. Unatoč činjenici da je riječki vodovod vodeći u Hrvatskoj, po sigurnosti vodoopskrbe i kvaliteti pitke vode, potrošnja u hotelima uglavnom se odnosi na sanitarnu vodu jer turisti nemaju naviku piti vodu iz vodovoda ili o takvoj mogućnosti nisu dovoljno informirani
